In which country? I think it’s generally not bad at all in, say, Norway, a big problem in many parts of the USA, still a problem but not as bad in other parts of the USA, and really atrocious in many other countries, and insane-o-bad in North Korea.
I think it’s always a problem in each specific instance that happens, and that it’s another very serious problem when a specific instance is not properly addressed and corrected.
And, even where it is a serious problem in the USA, it’s doesn’t apply to most police encounters. That it applies to any is a serious problem that should be addressed wherever & whenever it is a problem. The attempts at denial and cover-up seem like much more of a problem than people who may exaggerate the problems.
Of course it’s also not just about police behavior. There are also serious related problems in the USA in terms of what people are doing – crimes, gang activity, violence, etc., and there are cultural and economic problems that are related to those, too – racism, drug laws, economics & poverty, education, etc. All those things and more are related. It’s not like we just have to retrain the police and our problems will be solved.
